Answer 29

Hello,

Guys i am here to spread a message about some of the comments jiskha has been getting. First of all i would like to address the "Don't Cheat" issue. Let me make things clear. If you are on this site you are probably either cheating or checking your answers. So do NOT go on here and tell other people to "Stop Cheating" because you are also here and probably doing the same thing the rest of us here are. You don't need to continue talking about how cheating will get us in trouble and other things like that. Secondly, i would like to say something about how some of you guys are saying mean comments and things towards some of the teachers or admins here. Please stop saying things like " I hate you Mrs. Sue you don't help" or "Why don't you stupid teachers help us". That is just plain out rude guys. For one thing, they are here to help you. They aren't being rude or mean to you for not giving you the answers. Their job is to help you answer questions and get them right. They aren't here to answer your questions for you. Also, i really don't like the mean comments about Mrs. Sue. Mrs. Sue is dead guys and it is really offensive t those who knew her. So in all guys, please stop being rude and ruining this website for all that use it. If you agree with me on this post this on other questions too. Nobody should suffer from a lot of the bullying on this website. Thank you for reading this and have a good day. Annyeong! ( Goodbye )
